Build: v1.7 3632 (all builds for as long as I have been playing) Mode: Survival Mode: Any SERVER NAME: Any / N.a SEED-ID: not available. If applicable: MODIFIED PLAYFIELDS: No. Reproducibility: Intermittent. Severity: Major Type: Issue with signals. Summary: Signals though gates work intermittently. Description: A ramp connected to the output from an OR gate, with the inputs connected to various switches, works unreliably. In 99% of the cases, exit and reloading the game sorts out the issue. Rarely even just a Warp or teleport to another system and back will also cause it to reload and start working. Example and steps to reproduce: The output from an OR gate feeds to a hanger door and the ramp (inverted). One of the inputs is from a Control Panel Signal (named Manual Door Open) and the other input is from a motion sensor. As part of debugging, add 3 Lights. One light is set to follow the OR gate output and the other two respectively follow the two input signals (Manual Door Open and the Motion sensor). The expectation is that either input signal should consistently trigger the OR gate output. The experience is that it is unreliable. Sometimes nothing works, but that is rare. More often one or the other signal works. Occasionally it all works and any of the OR gate inputs will open the door as expected. For a more complex example that I have observed to have a much higher chance of misbehaving, use a 4-input OR gate. Connect it as above, with the extra inputs going to another sensor and a Lever (switch). Here the two motion sensors cover two different areas, eg outside and inside. Something else that consistently breaks it, is when attempting to use the output signal from a lever to turn any Sensor On/Off. Seems it all stops working the moment I do that and trying to undo the change results in it never working again, to the point where I've gone and deleted all signals, levers, and sensors, in order to "start over". This is sad as I would really like a way to use a Lever to temporarily turn the motion sensor off. In summary it seems that the more complex a signal setup is, the higher the likeliness of it misbehaving. Disclaimer: As a long time student of electronic cuircuits and coding logic, I have a solid understanding of the principles of AND / OR / XOR etc. I am confident that I have the signals configured correctly, and have experienced this issue over many builds and many ships and structures where I've tried to use it.
